problem
When I connect a USB cable between the printer and my computer, an “Unknown 
Device” message appears.
Note: This is not a problem in Windows 2000. Proceed with the software installation.

built up in the cable 
between the printer and 
your computer.

have the latest BIOS 
support for USB (contact 
your computer vendor).

2. Unplug the printer from its power cord.
3. Wait approximately 30 seconds.
4. Plug the power cord into the printer.

New Hardware Found dialog box (and you are not 
using Windows 2000), replace the USB cable.
